iMessage cannot activate after moving to new operator with same number (MNP)

Go to settings>iMessage and turn it off and on again.

Honestly I think you have tried everything, maybe talk to your carrier again? Always last resort too (apple store)

Can you send SMS at all?

In iMessage in settings, make sure mms, group messaging, and your phone number is the only thing set for send and receive.

Activation of iMessage requires the sending of hidden SMS to an apple server and depending upon where you are that could be an international SMS. are you able to send international SMS?

yes im able to send

Well I had to ask. You said that you could send SMS but I wanted to know whether that included INTERNATIONAL SMS messages because if you plan does not allow such messages then activation would be a problem

Hello. I had exactly the same problem, a few weeks ago I switched from Telcel operator to Movistar Mexico and iMessage / Facetime were unable to activate. The point is that in some plans, Movistar does not allow to send "international" SMS , even the fact that you have unlimited messages to national carriers ( within Mexico ). So you have to purchase an additional "recharge bag" starting from 30 MXN , which will allow your iPhone to send the SMS which will activate iMessage / Facetime. This was the fix ! Best regards.

In Spanish here :

Hola. Tuve exactamente el mismo problema, hace algunas semanas me cambie del operador Telcel a Movistar Mexico y entonces iMessage / Facetime ya no se podian activar. El punto es que en algunos "planes", Movistar no permite enviar SMS "internacionales", aun cuando tienes mensajes ilimitados a operadores nacionales ( dentro de Mexico ). Asi que lo que tienes que hacer es comprar una "bolsa adicional de recarga" que puede ser desde 30 pesos mexicanos, lo cual le permitira a tu iPhone que envie el SMS , que activara iMessage / Facetime. Esto soluciono el problema !. Saludos.

I have an old iPod Touch with old software that can no longer be updated:

iOS version 6.1.6

I've been searching for a solution to my iMessage login problem for months and tried everything from those frustrating links and all the tips from other users.

Here is what finally worked:

1) Settings > Privacy > Location Services > On

2) Settings > General > Date & Time > Set Automatically > On

3) Reboot device until Apple logo appears

4) Settings > Messages > Sign In
